What is so bad about chinese 49cc gas scooters?

I Have been wanting a 49cc gas scooter for a long time now. My grandpa and bike and moped sellers say they are bad because it's hard to get the parts.. Other than the parts are hard to get, what else is bad about them

I love my Chinese 49cc scoot. I upgraded everything to higher quality, though, from lines to tires to carb to rollers (sliders) and a lot more. To each his own. I've had ZERO issues getting the parts I need, fast. Not sure what that myth is about.

Little or no quality control of the materials used in the manufacturing of the scooter. Little or no quality control used in the techniques and processes used to construct the scooters. And the manufacturers know the crap they build will be exported so they won't have to deal with the fallout when - not if - those scooters go in the crapper.

No repair parts are available because the idea is that you ride it until it breaks, then you buy another one because they're so cheap that the cost of replacement parts would be close to the cost of a new one.

Avoid those scooters like the plague. And stay away from those 50cc machines in the first place. They don't have enough power to pull a greasy string out of a hog's butt. Get something bigger - 150-500CC's that will actually propel you at highway speed without running the guts out of it. Yamaha, Honda, Suzuki all build great scooters. INVEST your money in one of those instead of just SPENDING your money on some El Cheapo brand.

Most of the Chinese scooters and motorcycles use cloned engines, basically a copy of another company's engine. almost all of the scooters use a rip off of the GY6 engine, getting parts wouldn't be hard if you figure out what engine design was used. but honestly, i have seen 49cc cool sports scooters still in the crate for sale for under $700, so i personally wouldn't put a lot of time or money into repairs when they can be replaced so cheap

My recommend don't buy any Chinese brand, we Gov must ban sell here any Chinese brand, because are pure garbage. I was buy 49cc Chinese brand, after delivery became with problem, don't won start, send to repair cost 300$ and after I was use tree times and became with some problem, a choke is not working, when engine is cool like car, need a choke, who are electronic part, I was buy and change, nothing happening, is was cost my 1500$ and now I can use, because I have heavy arthritis in my hand, but is imposible sell. I will never buy made in China again.

Parts are not hard to find you can order online. Scooters and mopeds are becomeing more available because of gas prices.dont get me wrong some like roketa are junk but there are good ones 49cc are slow 30-35mph but there are tricks to unrestricted speed limiters on youtube.dont worry.

If you're not greatly experienced with motorcycles / scooters, try the simple things first: Replace the spark plug, a poor plug can give symptoms such as a weaker spark as the revs rise; which will cause running problems. Clean your air filter / cleaner, a sponge one can be washed and dried. Paper ones can be brushed off. If you feel that it's best to replace it all together, then do that; it's pretty cheap anyway.

Here is a lesson on reading between the lines.
If parts are hard to obtain, then there is a need for parts because said parts readily break.
Seriously, don't waste you money on a Chinese made scooter. Same is true of pocket bikes. Parts are poorly designed, poorly made, and use inferior materials during the manufacturing process.
That is the reason for the breakage. The parts break, and due to lack of parts, you ride sits in the garage collecting dust.
Save your money for a real motorcycle when you are of driving/riding age. Until then, ride a bicycle. Costs nothing to operate and will help you stay in shape.

You obviously did not listen to your relatives or the bike /moped sellers.
The cheap Chinese import bikes are rubbish and not even worth a second
look.They might look nice but they are badly made and not very reliable.
If you do buy one (god help you) you will experience problems with it in
the not so distant future.

Save your money and buy a reasonably new japanese machine.
Much better build quality and more reliable too.

They're made in a human rights violating, communist country that pay (sometimes) about 16 cents an hour to a 10 yr. kid to work 10-12 hours a day 6 days a week. Ain't that bad enough. I'm not counting all the Americans they killed in Korea and Vietnam.
